THEUREK G MAGHYWE NAILI'N UNITED .sra rns rA'i nNT ornion.

To all whom, it may) concern Be it known that I, Tiinorintn Jniiiv lll i- RIE THEURET, a citizen of the Republic of France, residing at Gaillon, France, have invented certain new and useful improvements in Nailin -Machines, of which the following is a speci cation.

My improvements refer more particularly to machines eni loyer insiiinlltaneouslydriv ing a number o nails after iii-st automatically placing such nails in their proper relative positions, and my im rovenients rim er such machines particular y useful in the manufac ture of articles such as packing-cases, crate-s,

&c., which are generally produce: in large quantities? and of equal sizes and configurations and wherein board and panels are to be attache" to their frames or main, bodies.

The objects of my invention are to provi e a nailing-machine of simple constructionan'l rapid and reliable in operation, whereby the nails may be arrange". automatically in their roper I la.t-lV6;pOSltl0nS, whether in straight ines or otherwise, and the parts which are to be joined together are automatically brought into positions in whicha hammer acts upon and ('rives sai nails simultaneously, thus doing away as faras practicable with manual labor.

In the machine, as hereinafter r"'escribe", the articles to be joiner together by nailing are placed in their proper relative po ions and are carried upon a horizontally iproeating platform to a position underneath a vertically-reciprocating hammer, while the platform istraveling towarfi theliaminer the nails re uire' in the nailing operation are autoniaticaly telivercd from a sorter to distributor, which places the same withtheir points downwar into. their proper positions with reference to the articles to he nailed. Magnets attached to the carriage hold the nails in such positions until they have been brought unterneath the hammer an i the lat ter has been lowered sufficiently to partly drive the same. with it the ma nets, are with rawnan; the hammer comp etcs the nailing operation. The elenchin of the nails takes place by passing the ratio es which have been nailed be tween suitable rollers.

= In the accompanyingdrawings, wherein corresponding letters an'fi figures of reference refer to cori'esponr mg parts, F gure 1 is a central longitutinal section of a nailing-ma;

ohine constructed according to my invention Specification of Letters Patent. Application filed August 29,1902. Serial No. 121,629.

Fig. 11 is a longitudinal section of part of the machine, showing the carriage on the point of starting upon' its return movement.

In the drawings, a, indicates an upright frani'e carrying vertical guides b, along-winch. a platform 0 and a hammer cl are adapted to travel. v

e is a main (t, which carries a pulley f, receivingits motion' through a belt, driven by any suitable niotor. Shaft c alsocarriesa conical pinion g and the enrless screw h. The transverse shaft i is mounted over the central portion of said frame and carries a toothed wheel j,- which engages with entless screw h and cams is 2m, Ai' other shaft it, place i. in the-same vertical plane with shaft i an l above the same, carries a conical pinion 0 engaging with pinion 9, another conical pinion p, antl toothed pinions g 9.; Above the frame a fly-wheel r is place :i the shaft of which carries a conical pinion 8, which engages with pinion 7i.

Two parallel horizontal main girders t t are fixedly mounted upon thefraine and carry rollers u u and guides o, mounted upon springs ac. Each of such girders carries the axis of pinionsy and 2, and'the axis of the-latter carries also a pinion 1 ,which coinniunicatesiby a sprocket-chain with one of the pinions q q. Upon the axis of the pinion zis articulated a shaft mounted upon the frame lever 12; the'head-of which carries two pinions 3 and tiwhich are always coacting, p nion y. A carriage 5-,. which travels between girders t tend rolls upon rollers a a, is provided underneath its lower surface with racks '6 6 and a cross-piece 7,.upon which magnet-' cams 9 9.

trlbuter and consists of a sieve constructed ofholders 8 8 are fixedly secured, and upon its 1 The hammer d carries-two sets of rollers 26 upper lateral edges there are provided cams l 26 and 27 27, which may be actuated by 9 9, arranged symmetrically.

A nail-distributor is provided comprising two lateral brackets 10 10, between which are arranged two series of planes inclined 1nversely. Each of said planes2 is constructed of copper wires so spaced as to permit the passa e between them of the shanks of the nailsfbut not of their heads, the shanks thereby becoming suspended vertically in the spaces and all the spaces being made to communicate with a channel of the same width, which leads to a socket 11, that is normally closed by a plate 10. All the plates 10 in the same series of planes 2 are mounted upon the same shank 13, the two shanks 13 being arranged side by side and parallel with the ines of intersection of the two series of planes 2 2, and the two shanks are provided, one at the left-hand extremity and the other at the right-hand extremity, with an arm carrying a roller 14, which is adapted to travel upon A nail-sorter surmounts the dismetallic wires or threads spaced in the same manner and for the same purpose as those forming the inclined planes 2 2. These threads are arranged parallel and in the same plane in the longitudinal direction of the machine and on each side of a transverse shaft 16, supported by the brackets 10 10 of the distributer. The threads 15areinclosed in a rectangular space, the longitudinal sides 17 of which are mounted upon shaft 16 and the transverse sides 18 18 of which are placed at right angles to the threads 15 and on their under sides are provided with teeth placed above the spaces between threads 15 in such manner as not to permit the falling of nails into the distributor unless the same are suspended-vertically between the threads 15 15 and to arrest the others, as shown in Fig. 5.

The brackets 10 10 are fixedly attached,

irespcctively, to the ends of the two arms 19,

articulated upon the axes 20 20, around which they are adapted to oscillate, together with the distributer.

To one of the ends of the shaft 16 there is keyed a lever 22, having a rectilineal slot with which engages a stud on the crank 21, which crank is keyed to the shaft of pinions 1 and 2, Fig. 1.

The magnet-holders consist of flat iron bars 8 8, having one of their ends fixedly attached to cross-piece 7 and at right angles thereto.

The iron horseshoe-magnets 24 are arranged at suitable distances upon the holders 8 8, which they straddle, and are confined there by brass bands 25 25, screwed to bars 8 8. The space between bands 25 25 and between the magnetsis filled out with putty. Said ma nets have their poles made tapering vertica 1v, so as to shape their ends in the form of vertical wedges.

cams Z and m. Camskk actuate levers 28 28, connected, by means of rods 29 29, to levers 12 -12, and each connecting-rod29is provided with a tooth 30, which is adapted to engage with a corresponding tooth 33 on bracket 101 The longitudinal girders t t are provided with abutments 31 31,- and the threads 2 2 of by endless screw h and toothed wheel j. Shaft n transmits its rotative movements to flywheel r by means of pinions p and s, and through the chains pinions q q impart rotative'movement to pinions 1 1, and consequently to pinions z 2. When pinions 2, 3, and y coact, the movement imparted to racks 6 .6 is a movement forward toward hammer (1, when. pinion 4 engages with pinion '51 this produces movement in the opposite direction, and when neither pinion 3 nor pinion 4 engages with pifiion y there is no movement im arted to rack 6 6. In accordance with the ength' of the nails em loyed the height of the sockets of the distri uter above the magnets 24 is regulated by raisin or lowering rods 32 in the grooves of brac ets 1O 10. .The boards or panels which are to be attached by means of nails are placed in a rectangular wooden frame 36, which confines the same in their respective positions. This frame is placed upon uides e v in contact with the abutments 31. he thickness of said frame 36 equals the distance between the magnet-holders 88 and the guides a) underneath'the same, and the cross-piece 7 of carriage 5 on. its under side is lower than the lower surfaces of the magnet-holders, its rear end being made tapermg, so that during the retrograde movement of the carriage, Fig. 9, said slope will cause the lowering of-irame' 36, held in contact with abutments 31 31, and will pass above the same, whereby springs or: supporting guides 12 will be compressed, and when cross piece 7 has passed the rear edge of frame 36 the latter, actuated by springs m at, will again take its place underneath magnet-car riers 8 8, During the forward movement of i driven to a certain extent the sockets containing the nails which are to are placed with frame 36 underneath ham mer d. Thereupon cams is k act upon levers 12S 28 and through connecting-rods 30 30 upon oscillating levers 12 12, so as to muse pinions 3 to be thrown out of engagementwith pinions i without pinions 4 being brought into gear with the latter. .e movement of the frame is therefore arrested. The cams 1 1 act then upon rollers 26 26, cause the hammer to descend, Fig. 1.1, and the nails are panels which are to be attached, Fig. hammer stops in its movement when it reaches aposition about two or three millimeters above the magnet-holders, and the nails are by that time driven in sufficiently so as to be rendered independent of the influence of the magnets. Cams Zr then again not iipon levers 28 28 to be lMOUghh into mesh with pinions y. The carriage 5 then starts upon its return move ment and another frame carrying boards or panels which are to be nailed is placed against abutments 3]. Cross connection 7 is withdrawn from the frame, which is held upon the platform 6 by hammer d, which rests upon same as the magnet-holders are withdrawn from the opposite hammer is again lowered and completes the driving in of the nails. Hammerd is in its lowest position when the carriage 5 is farthest removed therefrom and is being elevated while the carriage is again advancing toward the hami'ner. e same movements as described above again take place and the frame 36, which advancing, pushes the frame which has just been nailed beyond slides 12 and takes its place upon platform 0 of the machine. During the bacluvard movement of the carriage no nails must be permitted to be released by the distributer, and it therefore is necessary to then keep rollers 14 out of operative engagement with cams 9. For this purpose cams I: lit while employed in l'n'inging parts 4 and 11 into engagement raise conncct lug-rods 29, the teeth 30 of which actuate the tent h 3.; of the distributor and elevate the latter while turning it around the axes 20, so

that cams F) cannot any further affect rollers 14. The nails are thrown into sorter haphazard, the oscillating movement of which shaking the same up and spreads them out until they take vertical positions, as indicatedin Fig. 5, which permits the same to be introduced into the distributor, while the other Hulls are retained by the teeth of rakes 181m iililii-y assume the positions which are required. 'lhe oscillating movement of the orter is obtained by the rotation of crank 21, lhmpi'iijccl'imi hf which coii'nnunicates to lover 22 and shaft 76 the required.

so as to cause pinions 4,

rocking movement Tbe dowi'iwnid movement of the l l nails from thesorter to the distributer is prochine,

l duced by the trembling movement of the ma- 1 l i or if necessary, by suitable mechanical means. l Platform 0 is capable of sliding vertically ,l along guides 6, which permits of adjusting l the same at varying distances from hairline (1, according to the dimensions of the articles I which are to be nailed.

34 and 35 are two cylinders attached latl orally to the machineand arranged similarly l. to the cylinders in a rolling-mill and between which the panels which have been nailed are I purpose of completing the and clenching the points of conducted for the nailing operation I the nails.

I do not wish to confine myself to the del tails and detail combinations herein'set forth, as it will readily be seen that the same may be varied materially without departing from the spirit of my invention.
